No, this does no do anything, the bug is still present. * Deucher, Alexander <Alexander.Deucher@xxxxxxx> [2019-04-05 17:07:21 +0000]:
This may be related to stutter mode rather than gfxoff. If so, there is a fix in the pipeline for that. Does setting appending amdgpu.ppfeaturemask=0xfffdbfff on the kernel command line fix it?

By bissecting I found the cause is commit 005440066f929ba0dca8f4e0aebfbf8daac592cc. By reverting it the problem went out. I does not have idea about what to do next. Sorry if this should be posted to some bugzilla instead, I have got a bit lost. If so, would You please point my out what to do?
